Floodlight wi-if camera not working

Hibought this camera about a week ago, everything is working , until last night when my wi-fi went out , my wi-fi was restored this morning, but I turned on my cam it would not work, motion and light would not turn, i tryed to hard reset , resetting my router, check my wi-fi(it's over 2oo mbps, plus). so I decided to delete device and re-installed it but it won't connect to wi-fi(it's keeps showing the green light under the wi-if camera) isthere any other ways I can do to keep this working againthanks
